HPL Q16 - Understanding Error & Countermeasures Flashcards
Which of the following statements best fits the concept of latent error?
Select one:
a.Latent errors are detected rapidly.
b.Latent errors are mainly associated with the behaviour of frontline operators and are only detected after advanced problem solving.
c.Latent errors are rarely made by frontline operators and are consequently readily identified and detected by the monitoring, detection and warning links.
d.Latent errors may have been present in the system for a certain length of time and are difficult to identify as a result of the time lag between the generation and the occurrence of the error.

Between which two components of the SHELL model does misinterpretation of the analogue three-point altimeter occur?
a.Liveware-Software
b.Liveware-Liveware
c.Liveware-Environment
d.Liveware-Hardware
d.Liveware-Hardware
Which of the following statements best fits the definition of an active error? Active error is:
Select one:
a.Rare in frontline actions and difficult to detect owing to the fact that it usually occurs in a complex system of uncontrolled and involuntary deviations
b.Produced either by a frontline operator or by a remote operator and results in a hidden or latent consequence at a specific moment of the action.
c.Produced by the operator and can be rapidly detected.
d.Essentially results from the application of a bad rule or the poor application of a good rule by aeroplane designers.
c.Produced by the operator and can be rapidly detected.
What are the three error groups in the TEM model?
a.Communication, risk assessment, aircraft handling
b.Aircraft handling, ground navigation, aircraft configuration
c.Aircraft handling, procedural, communication
d.Procedural, aircraft configuration, situation awareness
c.Aircraft handling, procedural, communication
An unnoticed waypoint error is an example of
[latent error]
According to James Reason, what are different categories of error?
Select one:
a.Failures, omissions, deficiencies and flaws.
b.Faults, defects, weaknesses and oversights.
c.Defects, deficiencies, ambiguities and anomalies.
d.Slips, lapses, mistakes and violations.
d.Slips, lapses, mistakes and violations.
Which of these is an undesirable aircraft state according to the TEM model?
[Exceeding ATC speed restriction on approach]
Whilst in VMC en-route to the destination airfield in mountainous terrain, an instrument fails. The pilot decides to continue the flight. When nearing the destination airfield, the weather deteriorates to IMC conditions. The pilot continues with the flight and crashes into a mountain. What type of error is this?
a.Lapse error
b.Action slip
c.Design error
d.Error chain
d.Error chain
In 1989, an air Ontario aircraft crashed shortly after take-off from Dryden Municipal Airport during heavy snow. One of the causal factors of the accident was the reluctance of two cabin crew members to inform the flight crew about passenger concerns that the wings needed to be de-iced. This is an example of which type of external error generation factor?
Select one:
a.Social environment
b.Ergonomics.
c.Lack of knowledge.
d.Economics.
a.Social environment
Which of the following is the most important basis for a good safety culture?
Select one:
a.A critical incident stress management system.
b.A management willing to accept lessons learned.
c.An accident research group.
d.A non-punitive reporting system.
d.A non-punitive reporting system.
